Screw Jack Systems - Common Arrangements

Joyce jacks, miter gear boxes, couplings and motorized ComDRIVE® jack/actuators can be used in a number of system arrangements- like those pictured here. Because jacks selected for such systems have uniform lifting speeds and are fully synchronized, unevenly distributed loads can be raised, lowered and positioned in unison. Jacks of differing capacities may be used in the same system as long as driven shaft turns per 1" of travel are the same.

Joyce ComDRIVE motorized jack/actuators are particularly effective in multiple jack systems. Because ComDRIVE combines motor, jack and reducer into a single unit, the number of gear boxes, shafts and couplings in most arrangements can be reduced.

Note: Arrows indicate rotational direction to raise load.
